JOHNSON SPACE CENTER, Houston, Texas --- STS125-S-001 (December 2007) -- This STS-125 crew patch shows HST along with a representation of its many scientific discoveries. The overall structure and composition of the Universe is shown in blue and filled with planets, stars, and galaxies. The black background is indicative of the mysteries of dark-energy and dark-matter. The new instruments to be installed on HST during this mission, Wide Field Camera-3 and the Cosmic Origins Spectrograph, will make observations to help understand these unseen components which seem to dominate the structure of the Universe. The red border of the patch represents the red-shifted glow of the early Universe, and the limit of the Hubble's view into the cosmos. Upon completion of STS-125, the fifth mission to service HST, the Hubble will provide even deeper and more detailed views of the Universe. Soaring by the telescope is the space shuttle which initially deployed Hubble and has enabled astronauts to continually upgrade the telescope, significantly contributing to the expansion of human knowledge. The NASA insignia design for shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, it will be publicly announced.
